Wood summarises the route by first enumerating the seven passes which have to be negotiated before reaching Kunduz (or Khulm), and gives us a slight description of them all. Four of these passes were in Afghan territory, and three beyond. Of the passes of Ispahak and Unai he merely remarks that a mail-coach might be driven over them. The Hajigak group he regards as the "Key-guide to the Bamian line," the Hajigak being the highest pass encountered (about 11,000 feet). A little to the north is the Irak, and to the south is the Pushti Hajigak (Kafzur in modern maps); the Hajigak, or Irak, being open to khafilas for ten months of the year, but for a considerably less period to the passage of troops. The next pass Wood calls Kalloo (Panjpilan in our maps), which he regards as being lower than Hajigak. Then follows the descent into Bamian. Next is the Ak Robat Pass (10,200 feet), between the valleys of Bamian and Saighan, of which Wood reports that "it is open to wheeled traffic of all description." As far as this (the then frontier of Afghanistan) Wood refers to the fact, already recorded, that the Amir's Lieutenant--Haji Khan--was able to take field-pieces "of a size between 12- and 18-pounders." We already know the conditions under which this passage of artillery was effected. It is also on record that Nadir Shah took guns as far as Saighan. What is not so generally known is that the Uzbek chief, Murad Beg, took an 18-pounder over the rest of the route from Saighan to Kunduz. The three remaining passes are (1) the Dandan Shikan, between Saighan and Kamard, of which Wood reports the north face to be exceedingly difficult, and where he would never have believed that a gun could pass, had it not been actually traversed by the 18-pounder of Murad Beg. It may be mentioned here that it took 1100 men to drag that gun up the northern face of the pass, so that Wood is quite justified in classing it as only fit for camels. Then follows (2) the Kara Pass, leading from Kamard into the valley of the Tashkurghan River, about which the only remark made by Wood is that it may be turned by the pass of Surkh Kila (which involves a considerable detour). As Wood does not definitely state which is (3) the seventh pass, we may assume that it is the Shamsuddin, which is merely a detour to avoid an awkward reach of the Tashkurghan valley.
